PROBLEM TO BE SOLVED: To improve working accuracy of a can by preventing a vibration of a working tool unit. SOLUTION: A bottle-can making device 1 has a workpiece support table 10 for supporting a workpiece and a tool support table 20 for supporting the working tool 3 and works the workpiece by advancing or retreating the working tool 3 to or from the workpiece support table 10. The tool support table 20 is provided with the working tool unit 30 having a T-type base table 31 movable in an axial line of the workpiece W and a tool support disc with working tools 3 arranged in a circumferential direction, and a support rack 41 supporting the T-type base table 31. A concave groove part 41a extending in the axial direction is formed on the support rack 41, and a protrusion 34 engaged with the concave groove part 41a so as to be relatively movable in the axial direction is formed on the T-type base table 31. An electromagnetic coil is mounted on the inner surface of the concave groove part 41a, and a magnetic plate is mounted on the outer surface of the protrusion 34 while the concave groove part 41a is engaged with the protrusion 34.
